y
The UART is connected to the outside via the RJ-45 connector in front of the cabinet.
y
The UART uses OSC 1.8432 MHz clock as the Baud Rate source clock.
y
The default speed is 19.2 kbps and up to the maximum speed of 115.2 Kbps can be
supported by software.
EEPROM
y
The EEPROM to store MAC uses 3-Wire Serial 1kbit EEPROM(AT93C46, 128 byte)
y
The unique hardware number of a board is assigned in initial factory manufacture.
y
The EEPROM is connected to the Serial Peripheral Interface(SPI) in CPU for the
communication.
Reset
y
The reset chip uses DS1706RESA.
y
The types of the reset are power-on reset, push button reset, software reset, Watch Dog
reset, etc.
CPLD
y
The CPLD establishes the most logic for the TEPRI2 board and uses CPLD LC4256V-
75F by Lattice Inc.
y
The CPLD can be changed from the external PC via a JTAG bus.
IPC DPRAM
y
2-Kbyte DPRAM(71C132Y) is used for the IPC communication with the LP40 board.
y
IPC is operated in polling method.
Engine Block
y
STL7065 is used for the gain compensation of Tx/Rx highway of the TEPRI2 board.
